Oswald the Lucky Rabbit (also known as Oswald the Rabbit or Oswald Rabbit) is an anthropomorphic cartoon rabbit created by Walt Disney and Ub Iwerks for Universal Pictures. He starred in several animated short films released from 1927 to 1938. Walt Disney Studio produced a total of 27 animated Oswald one-reelers. After Universal removed Disney Studio from the Oswald series, Walt Disney and Ub Iwerks created Mickey Mouse as an obvious substitute.
